ctx7-cli

Original：🇺🇸 English
Translated

Use the ctx7 CLI to fetch library documentation, manage AI coding skills, and configure Context7 MCP. Activate when the user mentions "ctx7" or "context7", needs current docs for any library, wants to install/search/generate skills, or needs to set up Context7 for their AI coding agent.

ctx7 CLI

The Context7 CLI does three things: fetches up-to-date library documentation, manages AI coding skills, and sets up Context7 MCP for your editor.
Run with 
npx ctx7
(no install needed) or install globally with 
npm install -g ctx7
.

What this skill covers

  • Documentation — Fetch current docs for any library. Use when writing code, verifying API signatures, or when training data may be outdated.
  • Skills management — Install, search, suggest, list, remove, and generate AI coding skills.
  • Setup — Configure Context7 MCP for Claude Code / Cursor / OpenCode.

Quick Reference

bash
# Documentation
ctx7 library <name> [query]           # Step 1: resolve library ID
ctx7 docs <libraryId> <query>         # Step 2: fetch docs

# Skills
ctx7 skills install /owner/repo       # Install from a repo (interactive)
ctx7 skills install /owner/repo name  # Install a specific skill
ctx7 skills search <keywords>         # Search the registry
ctx7 skills suggest                   # Auto-suggest based on project deps
ctx7 skills list                      # List installed skills
ctx7 skills remove <name>             # Uninstall a skill
ctx7 skills generate                  # Generate a custom skill with AI (requires login)

# Setup
ctx7 setup                            # Configure Context7 MCP (interactive)
ctx7 login                            # Log in for higher rate limits + skill generation
ctx7 whoami                           # Check current login status

Authentication

bash
ctx7 login               # Opens browser for OAuth
ctx7 login --no-browser  # Prints URL instead of opening browser
ctx7 logout              # Clear stored tokens
ctx7 whoami              # Show current login status (name + email)
Most commands work without login. Exceptions: 
skills generate
always requires it; 
ctx7 setup
requires it unless 
--api-key
or 
--oauth
is passed. Login also unlocks higher rate limits on docs commands.
Set an API key via environment variable to skip interactive login entirely:
bash
export CONTEXT7_API_KEY=your_key

Common Mistakes

  • Library IDs require a 
    /
    prefix — 
    /facebook/react
    not 
    facebook/react
  • Always run 
    ctx7 library
    first — 
    ctx7 docs react "hooks"
    will fail without a valid ID
  • Repository format for skills is 
    /owner/repo
    — e.g., 
    ctx7 skills install /anthropics/skills
  • skills generate
    requires login — run 
    ctx7 login
    first
